I don't know how well that worked for him, but some days, I wonder. No matter how many times I tell my brain to come up with a new idea, it refuses to obey.
It could be because I haven't gotten any sleep the night before. It could be because I'm preoccupied with what's going on with the kids. It could be because after working so hard without a break, I'm burned out. Or it could be because it's Friday (hypothetically speaking, of course).
Some days, it seems like you've got nothing left in you to get your work done. Maybe you feel physically exhausted or emotionally bankrupt. Maybe your brain is fried or your spirit feels wrung out. Yet you've got a deadline or a boss breathing down your neck, and you have to get something done.
Some people meditate. Others go for a walk. Some do some kind of craft to keep their hands busy and their minds free. Others eats lots of chocolate!
What do you do when you have to work, but you feel like there's no work left in you?
